relates to MDEV-26505 Remove mariabackup --no-version-check... Open

 Description   

When using mariabackup to create a backup, I used the option --version-check along with the command. The command looked similar to the following:
/usr/bin/mariabackup --backup --user=<username> --password=<password> --galera-info --version-check --ssl --stream=xbstream | gzip - > /opt/backup/full/testbu.gz

The result of the command was:
/usr/bin/mariabackup: unknown option '--version-check'

why did you use it? what result did you expect?

mariabackup used to have this option (inherited from xtrabackup, surely), but not anymore. If it did what is documented for Percona xtrabackup, then it indeed doesn't make sense for mariabackup:

When launched with Version Check enabled, the tool that supports this feature connects to a Percona’s version check service via a secure HTTPS channel. It compares the locally installed version for possible updates, and also checks versions <...>

So it was probably the right way to remove it, although not very backward-compatible.

However, it is still documented in the KB, so it is a documentation bug to fix.

I have removed ##version-check## from the page. ##no-version-check" is however still present.
